in·duc·tion pe·ri·od

the period required for a specific agent to produce a disease; the interval from the causal action of a factor to initiation of disease, for example, the interval between exposure to radiation and the onset of leukemia; the interval between an initial injection of antigen and the appearance of demonstrable antibodies in the blood.

induction period

The time between exposure to a specific toxin or pathogen and the initiation of a pathology or disease of interest. Generally, the longer the induction period, the more difficult it is to link the putative cause and a disease, which compromises evaluation of causality.
